24-Pack Extra-Thick Sound-Absorbing Foam — 2″ x 12″ x 12″ Wall Soundproofing Panels; Fire-Resistant, Sound-Absorbing, and Echo-Eliminating; (12 Purple + 12 Black)

No need to purchase additional adhesives—simply peel and stick! This 24-pack set of thickened, self-adhesive acoustic foam panels is designed specifically for users who prioritize convenience. Each panel measures 12×12×2 inches and features a black pyramid profile; the back is pre-coated with a strong acrylic pressure-sensitive adhesive, protected by a release liner. The adhesive offers moderate initial tack, allowing for easy positioning and adjustment; once pressed firmly into place, the bond strength gradually increases, ensuring a secure attachment to flat walls, wood panels, glass, or metal surfaces. If removed carefully, the adhesive leaves minimal residue (we recommend testing on an inconspicuous area first). In terms of materials, the panels are made from high-density (28kg/m³) flame-retardant polyurethane foam; the pyramid structure efficiently absorbs vocal frequencies, computer fan noise, and sound reflections off walls. Each pack contains 24 panels—sufficient to cover a main wall in a standard home office or the ceiling of a recording studio. This product is particularly suitable for renters or for scenarios where drilling holes for installation is not desired. The black finish offers a subtle, versatile aesthetic that blends seamlessly with computer monitors and audio equipment.
